Swift Springs Expands 11" x 5" OD Conventional Spring Line with Four New Higher Rates
Swift Springs continues to grow its lineup of premium racing suspension products with the addition of four new higher spring rates to its popular 11-inch x 5-inch OD Conventional Spring series. Designed in response to customer demand from the asphalt racing community, these new springs provide additional setup options for teams competing in Pro Late Model and Asphalt Late Model racing.
The new additions include 450, 500, 550, and 600 lb/in spring rates, giving racers more flexibility when tuning chassis balance for changing track conditions and high-grip race surfaces.
Developed for Today's Asphalt Racers
The expansion of the 11-inch spring lineup came directly from racer feedback. Teams wanted higher-rate options that matched the quality and performance of Swift's existing 5-inch conventional spring lineup, and Swift responded by engineering four new springs that integrate seamlessly into existing suspension packages.
Whether preparing for weekly competition or major money-paying events, racers now have additional spring rate choices to fine-tune front suspension performance.
Built with Swift's Proprietary HS5.TW Material
Like every spring in the 11-inch Conventional Spring lineup, the new rates are manufactured using Swift Springs' proprietary HS5.TW material. This advanced spring steel is engineered to deliver exceptional consistency, durability, and repeatable performance throughout the racing season.
Combined with Swift's precision manufacturing process, racers can expect reliable spring rates and long-term performance race after race.
Designed for Performance
The new 11-inch Conventional Spring rates incorporate several engineering features that help maximize suspension performance:
- Full linear spring characteristics for predictable handling and chassis tuning
- Coil bind design engineered for high-load racing applications
- HS5.TW proprietary material for exceptional durability and consistency
- Designed specifically for Pro Late Model and Asphalt Late Model racing
These features provide racers with the confidence to make precise suspension adjustments while maintaining the consistency required at the highest levels of asphalt competition.
